      Mimi Zohar authored
      Start the policy_tokens and the associated enumeration from zero,
      simplifying the pt macro.

      security: don't use a negative Opt_err token index · 94c13f66
      Linus Torvalds authored
      The code uses a bitmap to check for duplicate tokens during parsing, and
      that doesn't work at all for the negative Opt_err token case.
      There is absolutely no reason to make Opt_err be negative, and in fact
      it only confuses things, since some of the affected functions actually
      return a positive Opt_xyz enum _or_ a regular negative error code (eg
      -EINVAL), and using -1 for Opt_err makes no sense.
      There are similar problems in ima_policy.c and key encryption, but they
      don't have the immediate bug wrt bitmap handing, and ima_policy.c in
      particular needs a different patch to make the enum values match the
      token array index.  Mimi is sending that separately.
